[PULL 49/49] Add a b4 configuration file

[Philippe Mathieu-Daudé]

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

b4 [1] is a convenient tool to manage patch series with mailing list
working flow.

Add a project default config file to match QEMU's mailing list conventions
as well as adopting differences on scripting.

Examples of b4:

    ```
    $ b4 prep --check
    Checking patches using:
      scripts/checkpatch.pl -q --terse --no-summary --mailback -
